MegaMatcher Automated Biometric Identification System

MegaMatcher Automated Biometric Identification System is a complete system for the deployment of large-scale multi-biometric projects.
The modular and customizable solution provides services for high-performance, scalable systems with multiple parallel transactions.

The solution is intended for national-scale projects, like biometric voter registration with records deduplication, passport issuing, border control, as well as other civil or criminal AFIS/ABIS.

Reliability Tests for Biometric Template Matching

MegaMatcher Automated Biometric Identification System includes Matching Service component, which is based on MegaMatcher Accelerator technology.
These fingerprints, faces and irises template databases were used for testing the reliability of the MegaMatcher Accelerator 11.0 template matching algorithm:

Irises database was created by merging iris images from BATH, Casia3 and ND-IRIS-0405 Iris Image Dataset.
The irises from those 3 datasets were combined to represent 1,500 unique persons with left and right irises captured in 5 sessions.
The tests were performed with these biometric template types:

1 iris record – using left eye image;

2 iris records – using both eye images belonging to the same person.

Multi-modal databases are combination of the mentioned fingerprint, face and iris databases.
The databases represent 1,500 unique persons with 10 fingerprints, 1 face and/or 2 iris images per persons, depending on the biometric modalities combination.
Each person's biometric data was captured in 5 sessions.
The tests were performed with the biometric template types, that combined 1, 2, 4, 8 or 10 fingerprints, 1 face and 1 or 2 irises, belonging to the same person, in all possible multi-modal combinations.

Reliability testing results for the MegaMatcher Accelerator 11.0 template matching engines are shown as a receiver operation characteristic (ROC) charts.
The ROC calculation was performed by comparing all templates from corresponding databases each to the other.
